I was thinking the same thing especially since the three are friends it seems in real life still (or at least from the sounds of it from stories that Saget tells in his standup routine). Maybe he wasn't available that night or something. Still would love if the three reunited for something.

I don't understand why this needed to be lip-synched and pre-recorded.

I guess I hadn't noticed it was. Maybe Stamos was out of practice singing? Either way the performance was fun for what it was, which was a fake band doing a reunion.

Coulier was doing stand up in Sacramento for the weekend (including Friday night)

He still has a job?

He's done standup for quite a while.
